JOHN zmsnrx, or Axnoiifomo, nssrenoa, n imam: assrenmnnrs, TO THErnosram-r1 commuw, INC., or snmcusn, n'aw roux, A CORPORATION or NEWYORK PRESS Application filed November 15, 1928. Serial 1161319370..

This invention relates toipresses and particularly that 'type of pressused for ironing or pressing clothing. 7

This class of press usually comprises a fixed lower buck and an upperhead mounted on an arm pivoted soas to swing the upper head towardorfrom the lower buck. Mechanisms of various types have been employed tooperate the swinging head, but these have" vention are attained in thepress illustrated, in the accompanying drawings and described below. Itis to be understood that the in- .vention is not limited to the specificform thereof shown and described.

Of the accompanying-drawings,

Figure 1 is a side elevation of a press emng the invention;

igure 2 is an enlarged side elevation of fithe upper portion thereof,partly in section;

Figure 3 is a section on line 3-3 of Figure 2'; a v Figure .4 is aperspective view of the press, partly broken away, and taken from therear of the press. Figure 5 is a view similar .to Figure 2 showing infull, parts omitted in Figure 2.

Referring to the drawings, the numeral designates a suitable supportingframe for the press on which the lower buck 11 of the fess ismounte'd.Frame 10 is provided with rackets .10 on' which is pivoted at 12!, 12=

I i "a pair of members 12it 12 comprising a lever secured to the upperead 1'3. A verticalguideway :14 is mounted on frame 10. between brackets10" and is proyided with partitions 14-, 14- defining pref;

erably three vertical passageways 15", 15 and 15, the two former toreceive vertically \ureciprocatory press opening and closing cam plates16, 16.v The plates 16 are provided with cam slots 16 forming shoulderscooperating with studs 12 on lever 12, the horizontal' portionsorshoulders of the slots acting'to raise and lower the'upper head topreliminary closed position and the vertical portions permittingmovement of a pressure applylng wedge plate or cam, to be described,while the press is closed. The verticalportions of the slots 16, inother words, permit relative movement of the cam plates 16 relatively tothe studs 12 after the press has been 65 preliminarily closedand'provide thereby a lost-motion connection between the actuatingmechanism and the motor means. The actuating mechanism is the mechanismabove described which closes the press.

The passageway 15 receivesa vertically reciprocable wedge plate or cam17 for applying pressure to the closed press, this plate having a wedgesurface 17 cooperating with a corresponding wedge surface 18 on a wedgeblock or cam 18 laterally reciprocable through apertures 19, 19and 20 inthe guidewa 14 and grooves 14*, 14 in partitions 14. lock 18 hasextensions 18", 18 on each side of wedge surface 18 fitting intoapertures 19 to slidably mount said block at its front end. The wedgeblock 18 preferably is interlocked with wedge plate 17 by'projections18, 18 thereon engaged in grooves 17 b so that the wedge block 18 isreciprocab-le by wedge plate 17. The upper rear end of wedge block 18 isformed with a wedge surface l8 operable to and from engagement with acooperating and correspondingly surfaced wedge ock 21 on the rear end oflever 12 in back of pivot 12. l The wedge plate 17 and the wedge block18'each form a cam for finally closing the press under heavy pressure.The cam formed by the wedge block 18 may be moved laterally by any meansother than the wedge plate 17 and, similarly, the cam formed by thewedge plate 17 may give lateral movement to the wedge block by its camo'r'wedge surface, which lateral movement may be 100 piston (not shown)connected byrod 23 to a cross head 24 on which cam plates 16 are mountedby means of rods 25, 25 and to which wedge plate 17 is secured at 26.Supply of fluid under pressure to either end of said cylinder may becontrolled by manually operable valve mechanism 27 connected between asupply line (not shown) and branches 28 and 29 to each end of cylinder22.

The operation of the press is best illustrated in Figure 2. When the camand wedge operating plates are in their lowermost position, the partsare in the full line positions shown. Upon actuating these up wardly,the cam plates with their shoulders pushing upwardly on the studs 12*,swing the upper press headdownwardly into preliminary closed positionwith the head preliminarily cooperating with the buck 11,

I studs '12 pass from the horizontal ,por-

tions of slots 16 into alignment with the "vertical or lost motionportions thereof during this operation and wedge block 18 movesrearwardly toward wedge block 21.

plates 16 and wedge plate 17 propels the wedge block 18 laterally sothat it engages with wedge block 21 and exerts the required pressure ofthe upper head downwardly on the work, cam plates 16 being inefiectiveon the arm 12 during this operation by reason of thestraight-verticalportions ofthe cam slots 16".

-Upon lowering of the cam, and wedge I plates after a pressing"operation, the wedge block 18 is first disengaged from block 21 and thenthe top edges of slots 16 of cam plates 16 engage studs 12 and puil therear end of lever 12 downwardly opening the press,

studs 12" moving into the horizontal portions of slots 16 by reason ofthe arcuate movement of the lever with respect to the straight movementof the cam plates. f

It will be noted "that regardless of the thickness of the work in thepress, the press will always apply the required pressure since withinworkable limits the relative angular position of arm 12 when closedontothe work only afiects the relative positions of the pressuretransmitting wedge blocks;-
